If you have a good competitive moveset for Machamp, post an answer below and upvote the best ones. Movesets for any of its pre-evolutions can also be shared on this thread.

Be sure to include full set details in your post, e.g. items, abilties, natures and EVs. Some detail, including the intended game mode for your set, is also appreciated. Access the full list of guidelines here.

Dynamic Punch / Cross Chop - Dynamic punch is super common and has that neat confuse rate. Although, I actually prefer Cross Chop ( I know, so weird.. ) because I love 100 base power moves that have high crit rates. Like Stone Edge... either way, both are good.

Dual Chop - Okay, not only is the animation really cool, but it's a really neat way to take out Multiscale Dragonite. If you're going full on Dragonite killer, then you need a completely different set overall. A set for killing Multiscale-Dragonite without rocks or assuming your rocks are already spun away would be using Flame Orb + Guts for the extra power. Once again, the only thing making Ice Punch inferior is that it gets weakened from Multiscale.

Stone Edge - I told you guys I like 100 BP moves with a high crit rate, didn't I? :3 ~ It hits hard for nice coverage. If you screw Dual Chop for something like bulk up, Ice Punch is an option here. Although Stone Edge has a high crit rate and gets accuracy boosted, etc.

Thunder Punch / Earthquake - This thing sadly gets walled by Jellicent easily. Guts + Flame orb path can make Stone Edge enough to take out Jellicent with a lucky crit, or something like that. Although without Guts boosting your attack, you're going to need a super effective hit. Or you can just rack some team support for that Jelly fish and go for some Earthquake action granting you Edge-Quake coverage.

So, this guy is NU now. Yeah... makes no sense to me either. I mean, this guy is much better than Hitmontop. And while Hitmonlee and Mienshao are good and deserve to be in UU, Machamp is Machamp! DynamicPunch just destroys everything. Stone Edge also makes use of No-Guard and gives nice type coverage along with nice power. Bullet Punch provides you with priority. And Ice Punch is there for taking down Gliscor (and also Landorus, but mainly Gliscor). It also does good damage on Dragon types. Life Orb lets you hit even harder. Your EVs provide you with some bulk, and maximizes your Attack. How is this incredibly powerful Pokemon NU? HOW?!?

Thunder/Ice Punch -(Cover Flying - Machamp has good defence so can take some flying hits)

EarthQuake (No point covering Psychic cause most psychics have high sp.attack and machamp has lower sp.def than defence so a big chance it would faint - and great power , used to deal with MANY pokemon )

Bulk-up is for boosting Attack and Defense. Dynamic-punch is for STAB and is a classic move for the Machamp family. Rock-slide covers Flying types. Earthquake is for coverage, while Bullet-punch would be for priority.

No Guard is the selling point of Machamp. Your teammates can use inaccurate attacks such as Blizzard and Zap Cannon and then end up destroying the foe. DynamicPunch is STAB that confuses. Rock Slide hits multiple foes, as does Earthquake. Wide Guard protects your teammates from multiple Pokemon hitting attacks.

That's not a bad moveset, but I would recommend holding Iron Ball instead of flame orb because, while it does help give you the Burn condition, you'll be sacrificing 100 Base Power for Fling because of your held item choices. I'd go with Iron Ball, and instead why not have a Pokemon on your team inflict a Burn on Machamp with Will-o-Wisp or Bestow to it, those are my suggestions for this moveset and Ability.

whoa this is old ;] but I have a set so I might as well share. I was taught this from someone...

Machamp @ Leftovers

Ability: No Guard

EVs: 252 HP / 252 Atk / 4 Spd

Nature: Adamant ( + Atk - SpAtk)

Moveset:

Substitute

Dynamic Punch

Payback

Ice Punch/Stone Edge

That HP makes Machamp very bulky, decent defences make it very hard to OHKO. Hitting of a sub allows a definite Dynamic Punch. The power it brings is very hard hitting, anything that doesn't get OHKOed will get a nasty case of confusion. And no Flying or Psychic type will like getting hit by a Payback or a stone edge.

Dynamic Punch - STAB, great power and will confuse target.
Cross Chop - STAB, great power and high critical hit ratio.
Earthquake - power deluxe and coverage.
Stone Edge - coverage and power plus a high critical hit ratio.

No guard machamp is deadly, it allows the use of low accuracy moves persoanlly I'd maxed out the PP of dynamic punch, and the sheer power of this Pokemon will just demolish all, plus with choice scarf it will outspeed some if not most Pokemon, allowing for a deadly first attack, if EV trained correctly, this Pokemon wont even need to worry about weaknesses.

OR

Machamp
Guts
@flame orb
Adamant
likes to fight
Atk and HP EV's

Close Combat - STAB, power and accuracy, just the unfortunate loss of defenses.
Sucker Punch - priority and coverage
Ice/Thunder Punch - coverage, decent power and a chance to freeze/paralyze respectively.
Facade - makes use of status condition and good power.

This set is very good as well, it has a better neutral coverage, and a priority move to help hide the defense losses, however sucker punch will help cover its low speed stat, making even an alakazam a low threat, all weaknesses are covered, with EV training and the combination of machamps high attack stat, flame orb, guts and facade, he really can cover all his weaknesses and knock out almost anything.

P.S if you want to, replace ice or thunder punch with stone edge, it has better coverage, better power, a high critical hit ratio but lower accuracy.
